IMPROVEMENT IN DEVICES FOR CAPPING AND UNCAPPING CARTRIDGES.

Specification forming part of Letters Patent No. 138,180, dated April22, 1873 application filed April 3, 1873.

To all whom it may concern:

Be it known that I, J osEPH F. NETTLEToN, of Branford, in the county ofNew Haven and State of Connecticut, have invented a new I1nprovement 1nCartridge-Brimers; and I do hereby declare the following, when taken inconnection with the accompanying drawing and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawing constitutes part of this specification, andrepresents, in-

Figure 1, a side view 5 .Fig. 2, a vertical central section.

This invention relates to a device for placing upon cartridge-shells thecap or primer which is inserted into a cavity upon the rear `end or headof the shell prior to charging the shell. This requires considerableforce in order to make the primer hold firmly in its place 5 and theinvention consists in a cylinder or support to hold the shell, combinedwith a lever, the nose of which is centrally over the said cylinder, andconstructed with a notch or project-ion upon the lever, so that when therim of the cartridge passes the said notch it will be held and preventedfrom removal, and the said cylinder provided with a vertically-movin gspindle for the purpose of ejecting or removing the exploded primer, thesaid notch acting as the resistance upon the shell to enable the saidspindle to be forced sufficiently hard against the primer.

A is a cylinder, the diameter of the shell to be primed, with aledge, B,at the bottom, upon which the open end of the shell rests, as seen inFig. 2. From this ledge a post, G, ex-

tends up above the said cylinder, to the upper end of which, as at c, alever, D, is pivoted. Within the cylinder A a follower, E, is placed,with a spindle, b, in its upper end, this spindle being' in the centerof the cylinder, and so as to loe pressed up through a correspondingperforation in the head of the cylinder. A spiral or other spring, F, isarranged upon or above the follower, the tendency of which is to holdthe spindle within the cylinder. The follower is prevented from leavingthe spindle by a stud, d, working in a slot in the cylinder. On theinner side of the lever and below the pivot a notch, f, is formed, insuch a position that, when the shell is upon the cylinder, this notchwill rest upon the head.

To prime a shell, place the shell upon the spindle H, as denoted in Fig.2, set the primer in place and raise the lever to the position denotedat H, broken line, Fig. 2, the nose bearing upon the primer and forcingit into place; the shell is then removed for charging. When thecartridge has been discharged, or if, for other purposes, it'isdesirable to remove the primer, place the shell in the same position. Inthus placing the shell, the rim will run down the face of the leveruntil below the pivot and approaching the notch f, it forces the leverback, as denoted at L, broken lines, until the head has passed the saidnotch; then the lever drops back, the notch extending over the head ofthe shell. Then take the lever, shell, and cylinder in one hand so as tohold the lever down, and strike upon the lower end or head of thefollower, which wiil force the spindle through the head and eject ordisconneet' the primer, leaving the shell ready for a new primer.

I do not wish to be understood as broadly claiming a device for primingcartridge-shells in which a lever is employed to force the primer intoplace; but

I claim as my invention- The herein described cartridge-primer,consisting of the cylinder A with its ledge B for the support of theshell, the lever D constructed with the notch f, and the follower E withits spindle blwithin the said cylinder, all substantially as set forth.

JOSEPH F. NETTLETON.
